The traditional steam turbine model considers the boiler as an infinite heat storage unit without considering the changes in main steam pressure,resulting in the main steam flow rate being only a func-tion of valve opening.However,in the actual process,the main steam pressure will fluctuate due to changes in boiler thermal storage status and turbine valve opening,and is not in a constant state.There-fore,if the influence of main steam pressure is ignored,the simulation accuracy of the built model will be severely limited.This article considers the factors of main steam pressure changes on the basis of tradi-tional steam turbine models,establishes a more refined steam turbine model,and studies the impact of main steam pressure on the dynamic response of the steam turbine through simulation.
